   en.wikipedia.org/wiki/Lens_fungus

   Lens or camera fungus is the popular name for the infestation of optical devices such as lenses, low pass filter (OLPF) or the camera sensor, by fungal threads (mycelium). By germination of fungal spores and further spore formation, the infestation can spread beyond the initial fungal network. The sensor or glass surfaces of the lens are ...

   Microfiber cloths are also used to clean photographic lenses as they absorb oily matter without being abrasive or leaving a residue, and are sold by major manufacturers such as Sinar, ZEISS, Nikon and Canon. Small microfiber cleaning cloths are commonly sold for cleaning computer screens, cameras, phones and eyeglasses. Cloth for cleaning glasses

4. Anti-reflective coating - Wikipedia

   en.wikipedia.org/wiki/Anti-reflective_coating

   The reflection from the coated lens is tinted because the coating works better at some wavelengths than others. An antireflective, antiglare or anti-reflection (AR) coating is a type of optical coating applied to the surface of lenses, other optical elements, and photovoltaic cells to reduce reflection. In typical imaging systems, this improves ...

   That distance is sometimes given on the filter in millimeters. A +3 close-up lens has a maximal working distance of 0.333 m or 333 mm. The magnification is the focal distance of the objective lens (f) divided by the focal distance of the close-up lens; i.e., the focal distance of the objective lens (in meters) multiplied by the diopter value (D) of the close-up lens:
